Quick verdict
LiftEvidence editorial assessment
A compact A-frame plate tree with seven posts for 2 in Olympic plates and a 500 lb rating, in a 22 × 19 in footprint. It is the most-reviewed plate storage here. Owners find it sturdy, quick to assemble and good value for plates from 2.5 to 45 lb. Stability with heavy plates is mixed, and some brands’ plates — owners mention Rogue — fit poorly on the posts. The rating is shared with the 5-post version.
